BURN-ER FOR GAS.

SPECIFICATION forming part of Letters Patent No. 350,815, dated October 12, 1886.

Application filed December i, 1885.

To aZZ whom it may concern.-

Be it known that we, EDWARD L. DAWES and Auous'r HAARLAXDE'R, citizens of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Im provements in Burners for Gas; and we do hereby declare the following to be afull,clear, and'exact description of the invention, reference being had to the accompanying drawing, which forms part of this specification.

This invention has relation to a novel construction of burner, which is particularly adapted for burning natural gas in fire-places, stoves, furnaces, &c., and has for its object the provision of a burner of simple and comparatively inexpensive construction, which maybe readily substituted for burners now in use, and in which the means for the admire ture of air and gas are so arranged as to give the best attainable results.

The invention consists in the novel construction, combination, and arrangement of parts, as hereinafter described and claimed, special reference being had to the following features of (-onstruction-vizz The provision of a burner composed of a casting in two parts, one of which is chambered and furnished with means for the ad mission of the gas and the escape of the same around the burner-tubes or air-nozzles, while the other is cast with tapering air-tubes, which rise through the gas-openings and to the level of or above the same, allowing the gas to rise above the surface of the casing and to mix with the air at the point of combustion.

Referring to the accompanying drawing, wherein is shown the improved burner in perspective, with portions of the casting broken away to illustrate the internal construction, A designates the body or casing of the burner, which consists of two parts, A A the part A being dished or cast with a cavity, a, and with an annular flange, I), while the part A consists of a fiat plate from which rise the tapering or conical tubes B B, and at the center of which is formed a threaded boss, 0, forthe attachment of the burner to the gas-supply pipe. The section or part A is cast with holes (Z (1, corresponding in posi- Serial No. 184,905. (No model.)

tion with the tubes B b,which rise to or above and pass into or through said holes, the latter being slightly larger in diameter than the tubes at that point where the tubes and surface of the part A coincide, so as to leave a narrow space or crevices around the tubes for the passage upward of the gas from the interior of the burner, such crevices being, preferably, continuous. The gas from the cavity or interior of the burner is in no way confined after escaping, butrises to the top of the air-tubes, through which pass a plentiful supply of air, mixes with the air at or above the tops of the tubes, and is there ignited and consumed. Ve have found that by this arrangement of the gas and air supply the flame, which would be otherwise contracted and small, is now spread and diffused,and the gas undergoes thorough combustion, produc ing a large and intensely hot flame, and one especially adapted for fireplaces and other localities where a-ilame of the desired character is required.

The action of this burner is peculiar. In practice the gas receives its supply of air wholly through and, by means of theair-tubes, the air being drawn very forcibly into the re gion of the flame by the suction or vacuum produced at the mouth ofthe tubes. The flame is thus a solid one, the gas being entirely coir sumed, and so spread as to entirely till the surrounding space.

\Ve do not claim, broadly, as our invention a burner consisting of a casing for the reception of gaseous fuel, having openings in the top for the escape of the vapor, and having a base with upright air-tubes passing through said openings, a burner of such character being already known. Having described our invention, what we claim, and desire to secure by Letters Patent, 1s-

The improved burner for natural gas,adapted for use in stoves, fire-places, and furnaces, and consisting of the two cast-iron sections A A-,thcsection A. bei ng flanged atb, and both sections secured together by bolts passing through said flange,said section A being of an inverted cup or dish shape, having openings (1 in its top for the escape of gas, while the section A is in the shape of a fiat plate, having cast 111- have hereunto set our hands this 3d day of tegral therewith the tapering air-tubes B,- 1 December, 1885.

which rise through and above the openings d, EDWARD L. DAWES.
